Abstract (en)
[origin: EP3640313A1] An object is to provide a refrigerant composition that is comprehensively excellent in various properties usually required of refrigerants, i.e., (1) low GWP, stability, and minimized temperature glide, as well as in essential properties required of alternative refrigerants for R404A, i.e., (2) refrigerating capacity, compressor outlet pressure, and COP that are substantially equivalent to those of R404A. In order to achieve this object, a composition containing a refrigerant is provided wherein the refrigerant contains difluoromethane (R32), trifluoroethylene (R1123), and 2,3,3,3-tetrafluoropropene (R1234yf) at a mass ratio that falls within the region surrounded by lines a, c and d, which connect the following three points in a ternary composition diagram ofFig. 1whose vertices represent the three components:point A (R32/R1123/R1234yf=25.6/13.4/61.0 mass%);point B (R32/R1123/R1234yf=25.6/3.4/71.0 mass%); andpoint C (R32/R1123/R1234yf=3.9/36.5/59.6 mass%).
